first of all, you can get geeked up from many differnt drugs including; meth, cocaine, ecstasy.
the feeling of being geeked up includes; talking rapidly, talking an excessive amount, not feeling the need for food or sleep. usually your senses are stronger, and your heart beats faster. some people may shake, get hot, sweat etc.
here's something most people don't think about when they get geeked up. geek drugs like cocaine, ice, etc. have come downs which is when the drug starts to wear off.
this feeling can make some people want to commit suicide, cry, and sometimes just break down.
if you are suicidal it's not in your best intrest to mess with any sort of drug, besides weed.
the time period that you are geeked up, depends on the drug, meth can last up to about 2 days.
cocaine lasts around 45 minutes.
ecstasy usually lasts anywhere from 3-6 hours. but i have experienced ex pills that last over 12.
before anyone tries any serious drug like all of these, they should seriously make sure they are going to be able, to make sure every time they do these drugs, they see the fine line between want and need. these drugs are very addictive, and can ruin your life, but if you have a hold on them they can be very pleasureable and fun.
